Abstract (en)
[origin: WO2008095190A2] Methods, systems, and devices are described for automatically converting audio input signal data into musical score representation data. Embodiments of the invention identify a change in frequency information from the audio signal that exceeds a first threshold value; identify a change in amplitude information from the audio signal that exceeds a second threshold value; and generate a note onset event, each note onset event representing a time location in the audio signal of at least one of an identified change in the frequency information that exceeds the first threshold value or an identified change in the amplitude information that exceeds the second threshold value. The generation of note onset events and other information from the audio input signal may be used to extract note pitch, note value, tempo, meter, key, instrumentation, and other score representation information.
